Spring Cloud Vault With k2 v2 - How to Avoid 403 at Startup?

Question

Problem

Does anyone know how to configure bootstrap.yml to tell Spring Cloud Vault to go to the correct path for k2 v2 and not try other paths first?

Details

I can successfully connect to my Vault, running k2 v2, but Spring Cloud will always try to connect to paths in the vault that don't exist, throwing a 403 on startup.

Status 403 Forbidden [secret/application]: permission denied; nested exception is org.springframework.web.client.HttpClientErrorException$Forbidden: 403 Forbidden

The above path, secret/application, doesn't exist because k2 v2 puts data in the path. For example: secret/data/application.

This isn't a show-stopper because Spring Cloud Vault does check other paths, including the correct one that has the data item in the path, but the fact a meaningless 403 is thrown during startup is like a splinter in my mind.

Ultimately, it does try the correct k2 v2 path

My configuration

    spring.cloud.vault:
      kv:
        enabled: true
        backend: secret
        profile-separator: '/'
        default-context: my-app
        application-name: my-app
      host: localhost
      port: 8200
      scheme: http
      authentication: TOKEN
      token: my-crazy-long-token-string

Thanks for your help!

Add the following lines in your bootstrap.yml, this disables the generic backend

spring.cloud.vault:
  generic:
    enabled: false
